A Valero gas station clerk was shaken up early Friday morning following a robbery.

Police said it happened just after 1 a.m. at the Valero on Southwest Military.

San Antonio police say an intoxicated man walked into the convenience store, told the clerk he had a gun and demanded cash.

The cashier gave him money and the suspect fled on foot. Police did not say how much cash was stolen. No arrests had been made as of 7 a.m. Friday.
